Scope: Celestron 9.25 Edge 235 mm at f/7, Laguna Mountains, CA 27 July 2013, Camera: ST8300M
Exposure: 13 x 9 minutes H-Alpha (2x2 bin), 8 x 6 minutes UV-IR Block Luminance (1x1 bin), 8 x 3 minutes RGB Exposures (2x2 bin)
Processing: Data Collection - CCDSoft (as FITs). Calibrated, stacked (Sigma Combine), LRGB channel registration, central gradient removal, and color equalization - Astroart. Curves, Levels, HaRGB combine and finishing - Photoshop. This image is a HaRGB combine with Ha channel and total RGB matched to minimize color shift. Selective sharpening was applied to nebula features. IR data was co-registered to the Ha data stack in Astroart and blended to red and green on the IR included images. RGB color calibration with eXcalibrator. Final Image size is approximately 2400 x 1800.
North is up in this image. Sharpless 101 is an emission nebula located in Cygnus. It is also known as Cederblad 173 adn LBN 168. It is popularly known as the "Tulip Nebula" due to its resemblance to that flower shape. This nebula lies approximately 6,000 light years distant from Earth. This image replaces an earlier image in the archives here. The Horizontal FOV is 38'.
Image center is located approximately - Equatorial 2000: RA: 20h 00m 02s Dec: +35°19'41"
Here WISE 12 micrometer sensor data is blended into the RGB image of Sharpless 101 - data is "add" applied into Green "screen" applied into Red.
